Abstract

An experimental investigation of the heat capacity of corrosion-resistant refractory nickel base alloy ChS88U-VI used as a material of the turbine blades for marine engines, blades of converted aircraft gas turbine engines and industrial gas turbine was carried out for the first time. The heat capacity of the alloy has been measured by the method of differential scanning calorimetry in the temperature range 300–1270 K of the solid state, including the phase transition region. The estimated error of the data obtained was 2–4%. The comparison with the promising nickel based superalloys Inconel 617 and Inconel 718 was made. Approximation equations and a table of recommended values of ChS88U-VI alloy heat capacity were developed for use in various engineering and scientific tasks.

摘要

首次对船用发动机涡轮叶片、改装航空燃气轮机叶片和工业燃气轮机叶片材料用耐腐蚀难熔镍基合金ChS88U-VI的热容进行了实验研究。采用差示扫描量热法测量了合金在300-1270 K固态温度范围内的热容量，包括相变区域。所获得数据的估计误差为 2-4%。与有前途的镍基高温合金 Inconel 617 和 Inconel 718 进行了比较。开发了 ChS88U-VI 合金热容的近似方程和推荐值表，用于各种工程和科学任务。
